WRINGER.

Application led .August 17, 1923.' Serial No. 657,858.

This invention relates t6 wringers.

It is the principal object o'f the rinvention to provide an improvedwringer, and particularly a wringer in ,which the rolls are readily released from and replaced and held in wringing relation.

With this generalJ object in view,the invention consists in the combinations, details of construction and arrangements of parts 10 which will iirst be described in connection with the accompanying drawings and then more particularly pointed out. v i

AIn the drawings- Fig. 1 is a v1ew partly in section and 16 partly'in side elevation ofa"wringer con-l structed in accordance with the invention;

Fig. 2 is a view ofthe same partly in plan and partly in'section;

Fig. 3 is a sectional view taken on the line.. 3-3 0f Fig. l;A

the frame comprises end plates`13, 14 and a side plate 15 formed in one piece and a sep-l arate side plate 16 cooperating with the" x single piece-to form a boxlike frame. To

securethe separate side plate in spaced position, the latter has two internally threaded bosses 17 which abut similar bosses 18 on the side -plate 15. Theparts are connected by screws 19 passing through the two sets of abutting bosses. Additional screws 20 ass through similar bosses 21, 22 near the ottom of the frame.

The side plates of the frame have correspending central openings 23, 24 for the passage ofthe articles passed between the rolls, and corresponding guide flanges 25, 26.

The ends of the frame have bottom ledges 30, 31 on which are sup ortedbearings for the shaft of the lower ro bearings are wooden blocks 32 having a free sliding tit in the channel formed by the side --and end plates of the frame. The blocks are grooved at the top for the reception of the ends rof the shaft 33 of the lower roll 12. The ends of the shaft 3 5 of the up er roll 11 are journaled in bearlng blocks 3g of the screws, being As shown, these which l arelike blocks 32 except that they face downwardly. The blocks 37 are alsoslidable in the frame and are forced toward the lower blocks to hold the rolls in operative wringing relation by means to .be described.

At one end of the frame, the right end as `viewed in Fig. 1, the roll shafts extend through a suitable slot Aor opening in the end plate 14 of the frame, and the extensions are provided with intermeshing duplex gears 38,39. The lower shaft has a squared end 40 bevond its -gear and is connected, by a coupling 41, with the squared end of drive shaft 42 to which power maybe applied in any suitable manner.

There `is provided means for releasably pressin the rolls together, which may coni venient y include a pair of coil springs and a spring-compressing supplemental frame element. Although capable of various constructions, in that here shown as an example, the main frame above described 'has an open upper rim. Telescoping over this rim is a frame top or cover 44. Near each end, this top has a threaded thimble 45 through which passes a spring-compressin screw 46 having an operating knob or han le 47. As -appears in Fig.l 1, the screws 46 extend downwardly in line with the shaft bearings and between the screws and the upper bearingv blocks are coil springs 48. 4As here shown, the lower end of each spring bears against an abutment plate 49 seated on the correspondin bearing block and havmg a spring-centering plug 50. The upper ends 'of the springs bear against similar abutment vplates 51, against which the ends Aofthe compressing screws 46 bear.

When the frame top 44 is moved down toward the rolls, the to telesco es down over the rim of the main 'rame an the ends forced against abutments 51, compress t e springs 48 and press the wringer rolls together in wringing relation. The parts are held in this position as hereinafter described. For a given position of the :frame-top, the degree of spring compression may be adjusted b. adjustment of the screws 46. When the rame top is released, the springs are free to expand, the top telescoping upwardly, and the rolls are thus freed from pressure.

There is provided means vfor releasably holding the supplemental frame element in spring-compressing position and returning it to such position alter a release. structures embodying the invention to the best advantage, this means includes mechanismplate 54. Passing through the upper end of Spindle 57, above the frame cover 44, is an emergency operating handle 58 by which the spindle may be turned. Mounted in the main frame a short distance below the open top thereof is an eye plate 59 having two oppositely disposed cam elements 60, the high points of which extend downwardly. The spindle 57 passes through the o ning or eye of plate 59 and has a curved ug 61A below each cam 60.

When the parts are in the position shown in Fig. 1, with the two sets of lugs at the high points of the corresponding cams, the frame top is held down with the ends of the screws 46 -holdin the springs com ressed and the springs, t rough the upper arin blocks 37, cause the upper roll to be presse against the lower roll. That is to say, the parts are in normal position for the wringing o eration. vThe degree of pressure can be ad]usted b means of screws 46.

Should it e desired to eect an emergency release of the roll pressure, a quick blow on the handle 58 is suieient. This rotates the spindle 57 to remove the lugs 56 and 61 from the highpoints of the corresponding cams, whereu n the frame top 44 is free to move u war y, thus allowing the springs to expan' In this connection zit is noted that the spindle 57, when inrelease position, is free to move upwardly with the top 44, the eye plate 59 having notches 62 for the passage of the lugs 61 on the spinf dle. Conseuently, in so far as the spindle is concerne and save for the provision of separate means hereinafter described, there is no limit to the relative u ward`movement of the top 44. The eye p ate 54 has similar notches 63 to permlt assembly and disassembly of the spindle. The release position is shown in Fig. 4. A

To reset the parts, the spindle 5'? is rotated to cause lugs 56 and 61 to ride up the corresponding cams, thus camming down the frame. top 44. This downward movement causes, through the engagement of screws 46 with the spring abutments 51, reeompression of the springs and repositioning of the rolls in normal operative position. When the lugs again reach the high oints of the cams, the frame top is again ocked down.

TWith the construction described there is a compound cam action. That is, there is a cam action between the spindle and the movable top and a cam action between the stationary frame and the spindle. As a result, the supplemental frame top may be returned to its spring-compressing position without releasing the screws 46.

ln the embodiment illustrated the cams 55 and 60 and the corresponding lugs 56 and 61 are double or reverse acting. Consequently the release handle 58 may be moved in either direction to effect release and in either direction toreset the parts.

ln the present embodiment the eye plate 59 is removably mounted in the frame. As shown, the plate has a width to lit freely between the frame side plates when. the separate plate is assembled. On the plate 59 are two pair of lugs 64 which are received by correspondmg pairs of holes formed in the side plates of the@ frame. By this construction, when the separate frame plate is in place the plate 59 is securely suspended in the frame. (Fig. 6).

There is provided releasable stop means.

for limiting the upward movement of frame top 44 upon releaseof the catch and expansion of the springs As here shown, secured to the top 44 are two loops 65 of wire formed with hook portions 66 at their lower ends. (Fig. 1) These hook portions 66 are located below the abutting bosses 17, 18 and hook under the bosses upon a given movement of the to 44 to limit lsuch movement. If/it is desire to disassemble the top, however, the loops can be sprungl inwardly to permit the hooks to pass by t e bosses, whereupon the top can be removed.

With the construction described, coil springs are used for ressing the rolls "into operative position.- t the same time, the construction is strong, compact and simple; the emergenc drelease is easily and quickly operated; an the arts are readily assembled and disassemb ed.

The operation of the wrin r will be clear from the above without furt er description.
